this is the question.\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "An inheritance of £400000 will provide how much at the end of each year for the next 20 years , if money is worth 7% compounded annually \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "for that, you need the following formula:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "ANNUITY FOR A PRESENT AMOUNT WITH END OF TIME PERIOD PAYMENTS \r
\n" ); document.write( "\n" ); document.write( "a = (p*r)/(1-(1/(1+r)^n)) \r
\n" ); document.write( "\n" ); document.write( "a is the annuity.
\n" ); document.write( "p is the present amount.
\n" ); document.write( "r is the interest rate per time period.
\n" ); document.write( "n is the number of time periods. \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "p = 400,000
\n" ); document.write( "r = .07
\n" ); document.write( "n = 20\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "formula becomes:\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "a = (400,000 * .07)/(1-(1/(1+.07)^20)) \r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "solve for a to get a = 37,757.1703\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "you can also use an online calculator that can be found at https://arachnoid.com/finance/index.html\r
\n" ); document.write( "
\n" ); document.write( "\n" ); document.write( "results from that calculator are shown below:\r
